Who called from 2139736461

They get spam from those breaking the law, and spoofing the number they're calling from.

Yes they unfortunately. More and more are dropping the home phones. Good thing is smartphones are mini computers. Smart and powerful. Apps and know-how puts the power back in your hand

same here

I have received several calls from this number but no message left.

Called land line. Hung up. No message.  I assume spam.
